Enable debug logging

It is possible to register for a notification which logs some useful information. This is achieved in the following way:

NotificationCenter.default.addObserver(self, selector: #selector(consoleLog), name: SmartpadConstants.Notification.consoleMessageRecieved, object: nil)

@objc func consoleLog(notification: Notification)
{  
   print("notification -> \(String(describing: notification))") 
}
